NOELREFILLABLE BOTTLE.

Application filed December 3, 1912.

i '0 all whom it may Concern Be it known that I, VVILLIAM H. DICKER- noon, a citizen of thellnited States, rcsiding in Cincinnati, in the county of llamilton and State of Ohio, have invented certain new and useful Improvements in Non- Refillable Bottles, of which the following is a specification.

My invention relates to novel means for preventing the refilling of bottles.

The object of my invention is to provide simple, economical and elllcient means for preventing the filling of a bottle more than once.

My invention consists in the novel means herein set forth andv claimed.

In the accompanying drawing which serves to illustrate the construction, and use of my invention: Figure 1 is a vertical section of the neck and upper portion of a bottle having my invention applied thereto. Fig. 2 is a similar view illustrating how the contents of the bottle may be discharged therefrom. Fig. 3 is a side elevation of my tapered, spiral, corrugated. noippull out glass plug. Fig. 4: is a top view of the same, Fig. 5 a bottom view thereof, and Fig. 6 is a side elevation of the elongated valve.

In the embodiment of my invention, as illustrated, and which shows a preferred construction 1 represents a bottle having a neck 2 provided with an inner annular ledge to form a valve seat The neck of the bottle is preferably formed in substantially the shape shown the opening at the outer end being tapered inwardly as at 4L, to receive the tapered spiral, corrugated, glass plug 5, and the ordinary cork or stopper 6. The shape of the opening below the point at which the glass plug 5 seats may be of substantially uniform diameter or of any form or shape desired down to the valve seat 3 and also below said valve seat as shown in the drawing. The interior of the neck of the bottle which engages the glass plug is provided with a ground surface 7. The glass plug is preferably formed with spiral grooves 8, extending from top to bottom, forming spiral ridges 9, the outer surfaces or edges of which are ground to correspond with the surface 7 of the interior of the neck of the bottle. The valve 10, is preferably formed oval shaped or elongated so that it will readily engage the valve seat 3, and close the opening against the passage of liquid inwardly, and Will also readily move Patented lDee. 8,1914.

Serial No. 735,809.

out of said seat when the bottle is turned to the position shown in Fig. 2.

lVhen it is desired to seal the bottle constructed in accordance with my invention the liquid is placed therein through the open neck 2, the valve 10 is dropped into position upon the valve seat the glass plug 5 is wedged into the position shown in Fig. '1 the ground surface of the ridges 9 engaging with the ground surface 7 of the bottle and binding said parts tightly and imn rcmovahly together after which the ordinary cork G is compressed into position as shown in 1. \Vheu it is desired to empty or partly empty the bottle all that is necessary is to remove the cork (3 and turn the bottle to the position shown in Fig. 2, permitting the valve 10 to unseat and the liquid to discharge therefrom and to pass out ot the neck of the bottle through the spiral grooves oi. the glass plug 5. As soon as the bottle turned to an upright position the valve 10 will automatically seat and as sumo the position shown in Fig. 1 so that if any effort r-rhould he made to refill the bottle by pourin liquid therein it will only pass downwardly through the spiral grooves and be prevented from entering the bottle by the valve 10 thus rendering it impracticable to attempt to use the bottle over again.

By making the grooves spiral the difii culty in removing the glass plug is increased since it would be practically impossible to introduce any instrument through the spiral grooves by which the plug could be disengaged and. pulled out. Besides the engagement and wedging together of the ground surface of the bottle and the plug, respectively makes it practicably impossible to disengage the lass plug after it has once been forced into tight engagement with the ground surface 7 of the interior of the neck 2 of the bottle.

The valve seat should be located some distance from the fixed position of the glass plug to permit the valve to readily seat and unseat for the purpose of preventing the passage of liquid into the bottle and to permit it to discharge the liquid from the bottle as th case may be. The valve is considerably smaller in diameter than the diameter of the opening between the valve seat 3 and the plug; 5 which permits the liquid when pouring it from the bottle to readily pass said valve.

It will be seen that my invention is one of great simplicity and one Which isadapted to successfully accomplish the desired result of preventing the refilling and re-use of bottles.

My intention is capable of some modification without material departure from the scope er spirit thereof.

1 claim:

In a noniefillable bottle having an interiorly and inwardly tapered neck with a valve seat therein and a valve seating on said seat, a guard for said valve consisting of a tapered plug with taper fitting the taper oi the neck, said plug being composed of a series of ridges radiating from a common center substantially at the axis of the plug and runnin spirally with relation to said axis, said ridges having thin edges constituting the taper of the plug and being uninterrupted throughout said taper, the up- Copies of this patent may be obtained for five cents 7 per ends of said ridges being substantially at right angles to the axis of the plug and being thin, the lower ends of said ridges being inclined to the axis downward to the center Where the ridges radiate from, and these lower edges being thin, the surface of said taper of the neck being rorghened and lVILLl-AM H.
